Aftermarket harness for a 05 SRX with Nav

I am trying to replace the navigation head unit with something new, I found a kit but I can not find a harness. The rumor I heard ( I work at a major aftermarket dealers headquarters) is that the nav unit is very proprietary and GMOS units will not retain door chimes, will not retain Bose amp on this specific year. Anyone know anything about this or have recommendations. I just want a new nav with Bluetooth and iPhone function.....HELP!

I see your in France, you do not have Onstar there? Your harness is for keeping Onstar, I used a different one for my 07
RP4-GM31 or

OK I see mine is not compatable with 05, mine is for 07-09 LAN 29bit

I checked all wires. It's good. But in harness of DVD+6CD changer+amplifier system, the audio wires go to CD changer and after go to the amplifier. I try PAC module with the CD changer connected but there is still no sound !
